But with a year left to run on his Leicester contract a transfer fee needed to be agreed to complete the deal.
And Toulon president Mourad Boudjellal has revealed that a deal has not been signed and that the Italian prop forward, who has 95 international caps, will not be playing in France next season.
"Martin Castrogiovanni is not within our means, it is clear," Boudjellal told local newspaper La Provence.
“When we do not have sufficient finances to hire a player, we do not. RCT cannot afford Castrogiovanni. The case is closed: Castrogiovanni will not play in Toulon."
For Tigers director of rugby Richard Cockerill the ongoing war of words could easily present a distraction ahead of the two side’s clashing in the Heineken Cup quarter finals this weekend.
But the former England international insists that all focus is on the match, particularly Castrogiovanni who has been a Tiger for seven years.
"Simon Cohen (Tigers chief executive) went to Toulon a couple of months ago and spoke to Mourad face to face," said Cockerill.
"They had a discussion and, in principle, did a deal that everyone was happy with. That has not changed at all – neither ethically or financially and now this statement (from Toulon) gets put out.
"Whether it is part of negotiating tactics from them or not, I don't know. It might be (mind games) but it doesn't affect us and Castro's attitude has been fantastic.”
